Apiece of yellow yard was 230 inches long. after 90 inches had been cut from it, the piece of yellow yarn was twice as long as piece of blue yarn. how much longer than the blue yarn was the yellow at first

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
